STEREOPTICON-SLIDE CARRIER.

To all whom it may concern Be it known that I, FREDERICK A. APPEL- nAUM, a citizen of theUnited States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new andImproved Stereopticon-Slide Carrier, of which the following is a full, clear, and exact def scription.

Among the principal objects which the present invention has in view are: to provide a slide having a movable member for use 1n conJunction with means rovided in the carrier for moving said mem r; to provide a carrier having a plurality of pockets for holding slides, and operative means in each of said pockets for operating said movable member; and to provide a carrier having operating means of the nature mentioned, furnished with manuallyoperable means for actuating the same.

In the drawings: Figure l is a side' view ofva carrier and slide therefor, both constructed and arranged in accordance with the present invention; Fig. 2 is a cross section on an enlarged scale, the section being taken on the line 2-2 in Fig. 1; Fig. 3 is showin the relative arrangement of and raming or a slide of the character named, said slide having a stationary and a single rotary memer Fig. 4 is a detail view on an enlarged scale showing a fragment of the rotary member of said slide; Fig. 5 is a detail view on an enlarged scale, showing a fragment of a stationary member with which the slides are provided; Fig. 6 is a cross-section of a slide constructed and arranged in accordance with a modication of the invention, wherein twovmovable members are employed.

The carrier 11 is of conventional form and construction, and is slidably mounted in a guideframe l2. The two sides ofthe guide frame 12 are provided with openlngs 13. The openings 13 are preferably somewhat smaller than the openings 14 provided in the two sides of the pocketed sections usual to carriers of this type. side of the pockets having the openings 14 is preferably slotted to admit to said pockas well as the kaleidoscopic or stereoscopic slides formed by the movable member 15 and the lstationarymember 16, as shown .in Fig. 2

of the drawings, and by the stationary meml Specification of Letters Patent. Application illed December 9, 1918. Serial No. 805,660.

The uppery ber 16 and the two movable members in the modified type shown in Fig. 6 of the drawings.

IThe movable members 15 are each providedwith a metallic gear toothed ring 17. The rmg 17 is suitably secured to the transparent or glassmember 15, the means shown in the drawings-for securing the same consisting of an adhesive strip 18, which is glued to the glass and to the ring 17. The movable members 15 and stationary member 16 are mounted in a frame 20, shown best in Fig. 6 ofthe drawing The movable members and the stationary member are held in Patented Nov. 3, 1914.

spaced relation by filling rings 21, which are xedly mountedl on the stationary member to form a'seat for the movable member. The stationary member 16 is preferably rectangular, as shown in Fig. 5 of the drawings, while the movable members 15 are preferably circular, as shown in Fig. 4 of the drawings. Circular recesses to receive said movable member or members, inclusive of the rings 17 carried thereby, are formed by solid sections 22 of the frame 20, which sections are slightly thicker than the movable members 15, to provide a certain freedom of movement therefor. The frame 20 overlies the sections 22 and the members 15, to form pockets to retain and guide said members l5.

The members 15 are mounted each on opposite sides of the member 16. Where one member l5 only is used, it is disposed at one side of the member 16, as best shown in Fig. 3 of the drawings. Whether'l one or two members 15 be used, the gear toothed ring 17 ofthe same engages one of the worms 23. The worms 23 are iixedly mounted on an elongated shaft 24, and are disposed directly below the centers of the openings 14 and the centers of the members 15 and 16, when the slides which they compose are dropped or placed in the pockets having said openings 14. The shaft 24 is extended lengthwise of the carrier 11 and mounted in bearings formed in the blocks 25 disposed in the runway or channel 26 which extends below said pockets. The

channel 26 is extended beyond the body ofV the carrier, to support the end bearing block 27 at a point removed from the end of the body of the carrier.

A bracket frame 28 is extended from the end of the carrier in position adjacent to the extension of the channel 26, said bracket frame being rovided to support a bearing for the driving gear wheel 29. Fixedl mounted upon the gear wheel 29 is a cran handle 30,' by means of which said wheel is manually rotated. The teeth of the wheel 29 are meshed` with the teeth of a small pin-A ion 31 ixed' upon the end of the .shaft 24.

' The ratio of difference inl size of the wheel 29 and the pinion 31 regulates the relative speed of rotation of said wheel and the shaft 24 and worms 23 mounted thereon.

As seen in Fig. 1 of the drawings, a carrier, such as 1l, being equipped with the shaft 24 and driving mechanism therefor, is first furnished with slides, to be exhibited when the openings 14 therein are moved in line with the openings 13 in the frame 12. When the slide having the members 15 and 16 is .in line with the openings 13 of' the frame 12, the operator grasps the crank handle 30, and by manlpulating it, rotates the shaft 24, which, through the medium of the worms 23, rotates the members 15.

As shown in Figs. 4 and 5 of the drawings, the members 15 and 16 are provided with radially-disposed curved lines. These lines are preferably 'oppositely pitched, so that when the member 15 is rotated, the'combined effect results in a centrifugal or centripetal roseate development. Other shapes and varieties of colors may be used to produce different designs or kaleidoscopic effects.

When using the two members 15, as shown in Fig.- 6 of thedrawings, the member 16 is generally ruled or igured to coperate with both o f the members, for the roduction' of a pleasing and pre-arranged e ect. e y

The carrier 11 i's provided with a handle# 32, by which it is moved in the frame 12.

The handle 32 is preferably pivoted by means of a Ein 33 on a lug 34 set out from the end of t e carrier 11. The handle 32 is thus pivoted so that it may be moved to the vertical position as shown in the dotted lines in Fig. Alof the drawings, andthus avoid interfering with the operator when manipulating the wheel 29 and the handle 30 connected therewith.

The stop pins 19 shown best in Fig. 4 of the drawmgs, are provided to limit the movement of the member 15 when it is desired to oscillate. said member. In this movement, the pins 19, striking upon an.obstruc tion of any suitable character placed in its path, prompts the operator tov-reverse the movement. Y

1. -In combination, a slide-carrier having a lurality of pockets; a rotary shaft mounte on said carrier, below said ockets; Aa plurality of worm gears extenl ing to YWithin said pockets and ixedly mounted on said shaft, one of said gears being in open communication with, and disposed in line with a radius of each of said ockets; a slide having a plurality of mem ers relatively'movable, saidmembers engaging said worm gears when placed in either of said pockets; and means for rotating said shaft.

2. An a paratus as characterized, c omprising a s ide embodying a stationary member; a rotary member; a gear-toothed ring fixedly mounted on said rotary member, said ring extending below said stationary member; and a 'frame slidably supporting 4said ring, for maintainin the same in line' with said stationary mem er, said frame having In testimony whereof I have signed my 'name to this specification in the presence of two subscribing witnesses.
